Material examined
Locality no. 1: CUMZ-CM002 (8 shells). Locality no. 2: CUMZ-CM006 (10 shells). Locality no. 5: CUMZ-CM011 (2 shells). Locality no. 7: CUMZ-CM013 (82 shells), CUMZ-CM014 (1 shell), CUMZ-CM015 (1 shell + 1 specimen in ethanol; Fig. 4B). Locality no. 9: CUMZ-CM034 (7 shells), CUMZ-CM035 (3 shells). Locality no. 10 CUMZ-CM052 (1 shell). Locality no. 12: CUMZ-CM093 (5 shells). Locality no. 13: CUMZ-CM120 (5 shells). Locality no. 17: CUMZ-CM135 (3 shells). Locality no. 18: CUMZ-CM143 (3 shells), CUMZ-CM144 (1 shell). Locality no. 16: CUMZ-CM166 (4 shells), CUMZ-CM177 (1 shell). Locality no. 6: CUMZ-CM174 (9 shells), CUMZ-CM175 (2 shells; Fig. 9E, F). The small juveniles were found on tree trunks and leaves, while the adults were found to live on the ground among leaf litter.
Distribution
Cambodia, Laos, Thailand and Vietnam (Schileyko 2011[2], Inkhavilay et al. 2019[1]).
Remarks
This species was originally described from “Cochinchina”. The distinguishing characters are a depressed-conic to conic shell shape and brownish shell colour. The last whorl is round to angular, with upper shell surface sculptured with fine radial ridges, below the periphery the surface is usually smooth. The aperture is sub-circular, with lip thickened in adult specimens. However, this species tends to have a highly variable shell from depressed-conic to dome-shaped shell, and the last whorl rounded (Fig. 9F) to angular (Fig. 9E).
The living snail has reticulated skin, yellowish to pale orange body, usually with dark longitudinal anterior stripes. Quantula weinkauffiana is considered to be a common species in Cambodia, where they can be found in both natural and highly disturbed human-modified habitats, such as agricultural plantations. Although Brumpt et al. (1968)[3] reported that Q. striata from Cambodia is an intermediate host of the rat lungworm Angiostrongylus cantonensis, the land snail species in that study was more likely Q. weinkauffiana.
